We don't know what the future carrying capacity of earth will be, and wild speculation there helps noone. We do know current carrying capacity appears to be too low but what is the best way to fix that? Is it telling the people who have many kids today - primarily the poor and uneducated - to have fewer kids? Is that likely to work? I believe Hans Rosling is right, who said birth rates are a direct consequence of how rich or poor you are. We've seen hundreds of millions lifted from poverty in the last few decades, with dropping birth rates as a result. The best action has to be to work to lift more out of poverty. Sitting in our ivory tower and declaring that people should have fewer kids is not going to work.
